Planning polyhouse farming in Sholingur? Sholingur is a small town in Tamil Nadu, home to about 31,000 people (GeoNames)[1][2], about 90 km from Chennai. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.

Climate for polyhouse farming in Sholingur

April is the hottest month in Sholingur, with average daily highs of about 38°C. January has the coolest nights, averaging 17°C.[3] The area gets about 1,058 mm of rain a year, most of it in July to November, peaking in October at about 202 mm. Average humidity stays at 75% or more in September to January, which raises the risk of leaf disease and slows evaporative cooling. Sholingur sits about 155 m above sea level.[2] On the Köppen–Geiger climate map, Sholingur falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Sholingur

  • Year-round crops

    Under cover, capsicum can be grown for the whole year in Sholingur, so you can supply buyers every week instead of one open-field season.

  • Better yield and price

    Plants grow without rain, hail and wind damage, so yields are higher and more even, and clean, graded produce sells at a better price, especially off-season.

  • Less water

    Drip irrigation under cover uses less water than flood irrigation, and the roof keeps October's 202 mm of rain off the crop and the soil.

  • Less pesticides

    Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (September to January), so you spray less often.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in Tamil Nadu can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]

Which polyhouse suits Sholingur?

For polyhouse farming in Sholingur, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to August, with moderate humidity of about 62%. In that dry air, wet pads can bring a 38°C April afternoon down to roughly 33°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. Capsicum, cucumber and tomato do well in a naturally ventilated polyhouse with a shade screen. If you want one structure, decide by crop: greens all year point to Fan & Pad; vine crops point to a naturally ventilated house.

Protected structures to compare

Plan for heavy rain in October (about 202 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.6 kWh per m² a day, so add a shade screen for leafy greens in the brightest months. A nethouse, the lowest-cost option, can grow hardy crops in December to February, when it is mild and fairly dry.

Crops for Sholingur

Based on Sholingur's climate, the crops with the longest growing windows are capsicum (all year), tomato (all year) and cucumber (all year). Capsicum fits all year with Fan & Pad cooling. Lilium and strawberry are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Sholingur.

Polyhouse farming in Sholingur: FAQs

Can a polyhouse farm run all year in Sholingur?

Yes, with the right structure. For Sholingur we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in March to August, so plan another crop for those months.

Which polyhouse is best for Sholingur?

With April highs of about 38°C and 58% average humidity in that month, we would start with Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.

Which crops should I grow in a polyhouse in Sholingur?

Going by the monthly climate, capsicum, tomato and cucumber have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Sholingur?

It can be, if the crop, the structure and the buyers match. In Sholingur, capsicum and tomato have the longest seasons under cover. Confirm prices and volumes with buyers first; our Detailed Project Report works out the cost, yield and returns for your plot.

Does Kryzen build polyhouses in Sholingur?

Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 800 km away, and we have built 9 projects in Tamil Nadu.

Is there a subsidy for polyhouse or hydroponic farms in Tamil Nadu?

Yes. Protected cultivation projects in Tamil Nadu can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department. Check the current rate and area limit when you apply.
